I To all whom 'it may concern:

Ohio, have invented certain new and useful Improvements in PortablevRail-Drills; and I dov declare the .following to be a `full, clear, andexact description. of the invention, such as 4will enable others skilledin the art to which it appertains to make and use the saine.y

My invention relates broadly to drilling machines and more particularlyto improvements in devices-of this character for use for. the purpose ofdrilling the rails or tracks of railways..

The main object of the invention is to iniprove upon devices of thischaracter to-such an extent as to provide a comparatively simplestructure possessing numerous ladvantageous features.

To the above end, a further object becomes to provide a main supportingframe formed iii two sections, and to equip said sections withindependent drilling and' clamping units, whereby, in certain cases, oneof the sections of the machine may be entirely removed and replaced by asupporting foot to be described. l

yYet another object is to provide new and novel means whereby the framemay be raised'out of contact with the track upon a` Apair of trucks,thereby rendering the device readily portable.

Yet other objects are to provide detachable operating connectionsbetween the two trucks and between the two sets of rail clamps, andtoprovide novel means wherematerial bein drilled.

4 W ith the a ove and numerOUsminOr objects in view, the inventionresides in certain i novel features of construction, fand-combirig. 6-is a detail horizontal section taken' nation 'herein described andclaimed and shown in the drawingswherein Figures 1 andy 2 are sideelevations of the machine takenfrom opposite sidesthereof; Figf3 isa topplan view; Fig. l is a bottom plan view; Fig. 5 is a vertical transversesection as seen on the line 5-5' of Fig. 1;

on the line 6-6 of Fig. 5: Fig. 7 is a verti- -cal transverse section asseen'on. the line 7 -7 of Fig. 6 Fig. 8 is a detail verticallongitudinal section taken on the line 8-8 of Fig. 6; Figs. 9 and 10 arevertical transverse by the drills may be properly fed into thev sectionstaken substantially upon` the'lines 9 9. 10-+1O of Fig. 3; Fig. `11 is adetail Figs. 15, 1G, 17 and 18 are detail vertical.

sections as seen o'n theline 15-15, 16-16, 17--17 andlS-lS of Fig. 14;Fig. 19 is a detail transverse section takenv on the line 19 19 of-Fig.20 and showing an end view of one of the chucks; Fig. Q0 is a plan view,partly in section, of one of the chucks; Figs. 2.1 and 2'2 are verticalsections as seen on lines 21-21 and 22-22 oflFig. 20; Fig. 23 is adetail longitudinal `section taken on the line of Fig. 19; Fig. ,2l is adetail perspective view of one of the clamping plates employed in thechucks; Fig.25 is a side elevation showing one erd of the machineremoved and the supporting foot applied; Fig. 26 `is a horizontalsectiontaken substantially on the line 26-26 of Fig. 25;

Fig. 27 is a top plan view ot' one end of the A 'the line Z9- 29 of Fig.1.

In the accompanying illustration the numeral 1 designates broadly a mainsupporting frame which includes a pair of parallel side bars, each barbeing formed in two sections Q and 2 which are connected at theirmeetingvends by plates 3 which are bolted to the outer sides thereof,said plates'being connected by a. transverseplate l which is joined tothe lower edges of the plates 3 and whiclrunderliesl the' inner endsofthe sections 2, a' similar plate being bolted to the lower side of thesections 9. The -sections 2. and 2 are hereshown as formed of angle ironbars having v.theirextrenie outer ends bent laterally outward las seenat 6 and 6', wherebvto provide supporting shoes designed to rest upon apair ot rails R when 'the device isin operation. f

vIn addition .tothe above named elements, the frame 1 includestransverse bars 7 and 7 which are'locatednear-its.oppositeends and other`transverse bars Sand 8., theformer supporting bearings 9and. 9.whichdepend therefrom, while the latter support vother bearings'lO'and 1-0.`

. For the purpose o-trussing the frame 1 to the necessary extent,acuteangularbrackl verse yoke members l19 which are secured be-v thehubs of pinions 18 ets llfand 11 depend from the two sections of theframe and are preferably vsecured to the side bars thereof, saidbrackets supporting transverse bars 12 vand 12 t'o which the oppositeends of longitudinal truss rods 13 neath the plates 5 and provided withopenings through which said shafts may slide.

rlhe opposite end of the machine is constructed in practically the samemanner as the end just described, a pair of parallel longitudinal shafts15 beingslidably mounted in the alined bearings 9 and 10 and ca rryingchucks 16 which, in turn, carry drills 17', the inner ends of saidshafts 15 being passed slidably yet non-rotatably through which are heldagainst longitunal movement by the bearings 10 and by yoke members19s'ecured beneath the plate 4.

Rising respectively from the plates 4 and 5 andfrom other appropriateparts, of the machine, are bearings 20 and 20, said bearings revolublysupporting driving gears 21 and 21 vfrom which shaftsextend inwardlytoward each other, said shafts carrying beveled gears 22 and 22 on theiradjacent ends. These beveled gears mesh with a beveled pinion 23 which,is rigidly keyed upon a transverse shaft 24, the latter beingrevoflubly mounted in a pair of motor supporting plates 25 which risefrom the inner ends of the sections 2. One end of the shaft 24 carries aspur gear 26 while the otherend'thereof may be provided with a suitablecrank 27, said gear 26 meshing with-a pinion 28 which is carried rigidlyby the crank shaft 29 of a suitable gasolene motor 30 which .is mountedupon the plates 25. By this construction, it will be seen that rotationof the crank 27 will "impart movement to the crank shaft of the motor30, which shaft is then driven by a piston within 7the cylinder of themotor, power then being transferred from said crank shaft 28 to thegears 21 and 21l and to the pinions 18 and 18, which in turn, impartrotary movement to the shafts 15 and 15, thereby driving the drills 17and '17 A.

For the purpose of feeding the shafts 15 and 15', the necessary extentto hold the drills into proper contact with the rails R, a pair .ofupright levers 40 and 40 is provided, said levers having their lowerends 4 and 12.) One set of the depend from transverse rock shafts -ingrail gripping lingers formed' in such a manner as to provide threetinedforks 41 and41, the4 lower ends of said forks being pivoted, by anysuitable means, to the transverse bars 12 and 12. The upper ends ofthelevers 40 and 40 are bent laterally inward as seen at 42 and 42 and areprovided with operating handles 43 and 43, with hook-shaped pawls 44'and44 and with operatingweights 45 and 45.

The noses of the hook-shaped pawls 44 and 44 normally engage shouldersformed by providing slots 46 and 46 in a horizontal plate 47 which isspaced above the motor and which is provided with notches 48 and 48 inits opposite ends, said notches normally receiving the levers 40 and 40.As seen in the various figures of the drawings, more particularly' inFig. 25, the plate 47 is supported upon a pair of arched standards 49and 49 which rise from the side plates 25, the standard 49 preferablycarrying a rod 50 by means of which the timer of the motor may becontrolled.

Pivoted to the forked lower ends of the levers 40 and 40 are links 60and 60, the other ends of said links being pivoted to thrust bearings 61which are constructed in a manner to be hereinafter set forth. -By thismeans, when the pawls 44 and 44 are raised from the position seen inFig. 1, to that seen in Fig. `2, the levers 40 and 40 may b'e swungoutwardly to the position seen in Fig. 2 in which position the links and60 will, through the instrumentality of the thrust bearings 61, forcethe shafts 15 and 15 outwardly to the proper extent to impart thenecessary pressure upon the drills 17 and 17. It will be understood thatthe weights 45 and 45 are designed for the purpose offl increasing theamount of pressure appliedto said drills.

For the-purpose of clamping the-machine rigidly upon the rails R, whenthe same is in operation, I preferably provide two lsets of clamps. (Seemore particularly Figs. 1, clamps comprises two pairs of slottedL-shaped bars 65 and 65 which are slidablysupported by passing suitablebolts through their slots and through the adjacent portions of thesections llt 2 and 2. The inner ends ofthe bars 65 and 65 are pivotedto'arms 66 and 66 which 67 and 67', said shafts being rocked to move thebars inwardly or outwardly, by hand le vers 68 and 68 which are providedwith suitable pawl and rack mechanisms for retaining them in adjustedposition. The second set of clamps comprises a pair of transverse shafts70 and 70 which are revolubly mounted respectively beneath the oppositeends of the bars 2 and 2, said shafts carryare designed to grip theunder sides of the heads of the rails R as seen in Fig. 1. The

71 and .71 which' shaft 70 is here shownl as provided with an operatingarm 72 to the upper end of which a link 73 is pivoted, the other end ofsaid link being pivoted to the lower end of an angular handfl'eve'r 7 4which is pivoted at toa rack 76 which rises from one of the sectionsl 2,said lever being provided with a suitable pawl 77 whereby it may belocked against movement. .Removably connected at 7 8 with the eXtremelower end of the lever 74,V at a point .beneath the connection of thelink 73 is a longitudinal operating rod `7 9 whose other end is pivotedto the lower end of an operating arm 8O which depends-from the shaft 70.It will, therefore, be seen that actuation of the lever 74 willsimultaneously apply both sets of fingers 71 and 71.

ln connection with the mechanism, above described, I prefer to employmeans whereby the entire frame and the parts carried thereby may beraised out of Contact with the rails R for the purpose of transportingthe machine from place to place. For this purpose, a pair of trucksdesignated broadly by the numerals and 85, 'is provided. ,Since theconstruction of each trunk is iden* tical, but one will be described.

As most clearlv seen in Figs. 9 and 10,'

the truck 85 is illustrated, said truck comprising a pair of flangedsupporting wheels 86 whose aXes are spaced and positioned in parallelplanes, said aXes being connected by va pair of parallel bars 87 havingtheir opposite ends bulged'outwardly' for the reception vof the wheels.Secured, by means of'bolts orother suitable means between 'the bars 87,is a pair ofupright bearings 88.

which .receive upright'rods 89 rising from the laterally turned ends ofthe main frame 1, said rods being here shown as Aprovided l with'suitablebraces 90 which are connected to their upper ends and to theframe 1. Mounted!4 between the side bars 87 and between thebearings 88,are two levers 91 and 92the inner end of the formeroverlying the -innerend of the latter and being connected 'thereto by a link 93. rllheopposite end of erat-ing shaft 98 which is -formedfin twoy sec# tionsconnected by a sleeve 99 which'is.` provided with suitable set screws.

vBy reference to the drawings, kit will be Y* seen that the stru'cturejust described, is. duplicated on both endsof the ,frame and that acrank arm 97 is carriedby each end n of the shaft 98.- It willfurtherbeseen that said shaft 98 is provided withl an operating`.standard 103.which rises from one of v'sections 2. The nose of saidcatch 101 only engages said notch when the lever 101 is operated toraise theentire frame and parts carried thereby,upon the two trucks, itbe u ing understood that partial rotation ofthe shaft 98 will accomplishthis result, through the instrumentality of the' arms 97, links 94, and96, and levers 91 and. 92.

, Althoughanyappropriate form vcould be employed, the chucks 16 and 16"are preferably constructed yas-seen from Figs. 19V to 24 inclusive; thechucks 16 being here shown. This chuck 16 includes ahead 105 which isprovided with a slot 106 which opens through one of its sides andthrough one of its ends, said...slot being preferably enlarged `at itscentral portion for the reception of av clamping plate 107 which slidesthereinand which may be forced'inwardly against the shank of the drillbya set screw 108 which-is threaded through a ring orsleeve 1.09, the.latter encircling the head 105 as clearly illustrated. As above stated,otherv forms of f cent parallel drill operatingishafts, said shouldersbeing surrounded by sleeves 111 which are of greater length than saidshoul- ,keyed, by any suitable means, tothe adjai ders, therebyproviding an annular space within which a' series of ball bearings 112may be placed,'said bearings being retained in position by a :transverseplate 113 having openings through which the shafts' pass,

' ywhile a'second plate 114'and a pair of bolts 115, are provided forthe purpose of securing the Vplate 113 imposition.'` By reference moreparticularly to Fig. 14it' will be seen that the bolts 115 pass through,the 4opposite ends of the plates' 113 and 114, said ends'` projecting`beyondl the sleeves 111, whilel anotherI bolt 116, herein shown intheform of an eye bolt, passes through thecentral portions of said platesbetween 'the two sleeves. It is to this eye bolt-11`6 and to a pair ofears 117 formed integrally with the opposite ends ofthe plate'113, thatthe links 60 and 60 are pivoted, this construction and arrangement' ofparts. ,producing` an" eX- tremelyA advantageous device, since the ythrust, exerted by the levers 40v and 40 is evenly distributed uponthe'thrustbeaifings. {lili-oni the foregoing description takeninconnection with the accompanyingdrawings, it will be seen thatacomparatively simple machine hasbeen provided for carrying out theobjects of the invention, yet

one which possesses a number of advantages.

4. Still another advantage I the machine, as above describedl and asillustrated in the drawings, is now to be'set forth. Itis a well knownfact that a device, constructed as above described could not well beemployed for drilling frogs or other peculiar formations along the tracksince it becomes necessarylto retract the drills to an extent whichwouldl not be1 allowed by-such construction. i

For this purpose, the entire left end of the machine, when viewed asseen in Fig. 1, is removedby disconnecting the plates 3 from thesections 2, by removing certain of the nuts 14 upon the truss rods 13',by loosening the set screws of the sleeves 99 and`by disconnectingtheoperating rod 79 from the lower end of the lever 74. If desired, thedetachable braces 90 may be likewise removed thereby allowing tlie truckS5 to be disconnected from the remainder of the device, in whichcase,-it will beunderstood that one end of the section or shaft 98 andthe lever 100 will be removed with Said truck.

Altering the device, as above described, does not affect the operationof the drills 17, or that ofthe clamps 65 and 71, in any manl ner sincethe lever 74 is mounted upon the .being understood tliatthe lever 68 isemployed for operating the clamps G5.

For the purpose of supporting the inner end of the frame when the leftend of the machine is detached, as seen in Fig. 25, a foot 125' isemployed, said foot being herein shown in the form of a transversebar-designed to rest upon the cross ties, and a pair of invertedL-shaped attaching brackets 126 which rise from. said bar and whose horiZontal arms are provided with bolt holes to receive the bolts 127- whichpreviously secured the plates 3 in active position. It will be notedthat the motor, or power plant, is mounted upon the right hand end'ofthe machine, this being advantageous since the sainev may now beemployed for the purpose of driving the drills 17.

From the last fewparagraphs of description, taken in connection with thepreceding explanation, it is thought that the device will be'clearlyunderstood and that its numerous advantages will be readily understoodby those skilled in the art to which the inven tion relates.
